Patented Dee-2o, i932 UNITED STATES PATENT. OFFICE HENRY WOGHNER, 01 BOOK ISLAND, ILLINOIS, ABSIGNOB T BEAR HANUFAW COMPANY, 01' BOOK ISLAND, II'JIIFIOIS AUTOMOBILE FBAIE STBAIGHTENHQ'G MACHINE application filed September as, 1931. Serial No. 564,577.

similar machine of that type for which application for Letters Patent of the United States was filed by myself MayA, 1931, Serial No. 534,889. By means of the present improvement the scope and usefulness of the machine are greatly enlarged.

The chief purpose of a machine of the kind named is to provide means for support of a motor vehicle in convenient position for the straightening of the frame thereof, or for other operations thereon, and in connection therewith to provide a substantial support or anchorage for instruments or tools that are to be used in connection with the straightening operations. Such means are shown in said former. application, and the present invention relates chiefly to auxiliary supporting means, which can be conveniently used either alone, or in conjunction with the original supporting devices of the machine.

On account of the heavy character \of the work to be done by machines of this class the supports must be of a rigid type, and as set forth herein they consist of angle-plates or I-beams, with longitudinal spaces to accommodate bolts or other fastening devices.

In the accompanying dravving,

, Fi I is a cross-section of amachine embodylng the invention, on the broken line 11 of Fig. II. V m

Fig. II is a fragmentary plan view thereof.

Fig. III is an end view ofthe beam 16.

A pair of tracks of an automobile runway is indicated at 5 and 6, each provided with side flan es 7, and supported at their ends on crossams 8, mounted on angle-blocks9. Fixed to the lower faces of the tracks 5 and 6 are channel-plates 10, with their flanges turned inwardly, and spaced therefrom are I-beams 11, also attached to the lower faces ,of the tracks'5 and 6. The adjacent lower flanges ofsaid angle-plates 10 and I-beams v11 are spaced and provide supports for hangers 12,-in'which are supported cross-beams 13, providedwith longitudinal openings 14. That part of the mechanism hereinbefore described is substantially the same as that plates supported from said-tracks in forth in said former application, with the exception that the flanges 15 of the I-beamS 1 1 providesupports for the ends of a-rela-- tlvely short beam 16, having a longtudinal space 17 for the passage of bolts and the like. The hangers 12 are capable of adjustment longitudinally of their su ports, and the beam 16 can also be move position between the eye-beams 11. By turning the same at an angle withthe I-beams the beam 16 can be readily removed or replaced. Any desired number of said beams may be employed at different points in the machine, the purpose thereof being similar to that of the beams 13,-namely, to support mechanical jacks, straightenin frames, grapples, or other tools used in the arm straightenin operations. Such tools can be supported t ereon at a greater height than on the beams 13, and in many cases the work can be performed by employin the beams 16 alone. In other cases it will convenient to use one of each of said beams, anddesired adjustments in the relative positions of said beams to or from each other can be made.

to any desired By removing the beam 16 from the machine originally designed.

it can be used-with the beams13 alone, as

to-secure by Letters atent, is:

1. An automobile frame straighteni machine, comprising1 means'for support t ereof,a pair of angleara lel spaced relation with each other, I- eams a pair of tracks an supported from said tracks in parallel spaced re ation with each other, and in parallel spaced relation with said angle-plates, to form run-ways for cross-beam supports, and one or more cross-beams supported at their ends by'said I-beams.

2. In a device of the class described, a-pair of longitudinal supports, a pair of platessuspended from each of'said supports, provided with coacting flanges forming tracks for a hanger mechanism, hangers su ported fiangeson-the innermost o u said plates ing a beam support. r

3. In a device of the class described,&

on said tracks and op ositely isposed ormpair of longitudinal supports, a pair of plates suspended from each of said supports 1n parallel spaced relation with each other, and provided with coacting flanges forming runways for hangers, hangers movable in said runways, hangers, coacting flanges on the inner faces of the innermost lates forming a beam support, and a crossearn mounted on said lastnamed flanges.

4. In a device of the class described, a pair of tracks and supports therefor, hanger runways supported from said tracks, hangers supported in said runways and movable longitudinally thereof, cross-beams mounted in said hangers, beam supporting means between said runways, and one or more beams mounted in said last-named means, and adjustable therein, longitudinally of said tracks.

In testimony whereof, I afilx my signature.
